Two men were charged with holding up the store in East Windsor at knifepoint earlier this week, according to police.
Residents Michael Shawn Kee, 18, and Malcolm Jamal Browne, 19, threatened two female employees with a "large knife" on Monday and forced them to open the safe, police said. The robbers stole an undisclosed amount of cash and one of the victims cell phones, and broke the other employee's cell phone.
Police said the men hid in the store until closing before they robbed it. No one was injured.
Kee was charged Wednesday, and Browne was charged Thursday with robbery, weapons offenses, terroristic threats, theft and burglary, and were being held at the Mercer County Detention Center on $100,000 bail. Browne turned himself in to police.
